With the news going crazy these days, I felt like there is one particularly thing that is often misunderstood. The corona virus spreads exponentially (without intervention or measures). The problem is that we – as human beings – are very bad at imagining what an exponential trend looks like. By now, many differnet graphics and figures appear everywhere that aim to visualize the amount of infections or mortality rates per country. One of the most… Read More »Understanding exponential growth: The corona pandemic

Computing a priori power analyses for simple statistical models can be done analytically (e.g., with G*Power or the pwr package in R). However, estimating the power for more complex models and in particular structural equation models (SEM) is not as straightforward and requires simulations. I recently came across the package paramtest (Hughes, 2017) which provides a great framework for conducting more complex power simulations. In what follows, I provide some examples of how to simulate… Read More »Estimating power for structural equation models: Simulations in R

Welcome!

I am a researcher in the field of communication science working at the Department of Communication at the Johannes Gutenberg University Mainz (Germany). Previously, I was a research assistant at the University of Hohenheim (Germany) and a visiting scholar at the Cornell University (Ithaca, USA). On this website, you can find information about my research interests, publications, teachings, and some personal background.

From time to time, I take pictures of things and people. You can find them here.
